Large Scale Central

What kind of switch?

What kind of switch do I need for volume control on a Sierra Soundtrax card? I need to add one to my Pacific’s card.

Spring-loaded center off, same as used on Phoenix, but not the stiff ribbon cable.

Thanks, Dave.
Would that be a DPST-center off -spring loaded center off?

SPDT, isn’t it?
I have the Sierra ones, already wired, going to the Post Office tomorrow

Yuo can use two small micro normally open push button switches.

I use them on my Shay, they can be hidden easier on the tender coal door.

Wire one side of each push button as common and then select which one will be volume up and the other as volume down.

On the Tender coal door I added a toggle switch also to turn the sound off and on, this is why I used the push buttons so I did not confused myself in the operation.

Dave,
You have Email.
